From a9cdf410ca8f59b52bc7061a6751050010c7cc5b Mon Sep 17 00:00:00 2001 From: Keith Owens Date: Mon, 10 Apr 2006 22:54:07 -0700 Subject: [PATCH] [PATCH] Reinstate const in next_thread() Before commit 47e65328a7b1cdfc4e3102e50d60faf94ebba7d3, next_thread() took a const task_t. Reinstate the const qualifier, getting the next thread never changes the current thread.
